Advantages of Aluminum Squeeze Casting Over Die Casting

As a professional manufacturer based in China, CEX Casting specializes in producing aluminum die casting, aluminum squeeze casting, and CNC machining parts.

In this article, we will provide a detailed comparison between aluminum die casting and aluminum squeeze casting from the perspective of CEX Casting, showcasing why aluminum squeeze casting stands out as the superior choice.

Process Overview

Aluminum Die Casting: this process involves injecting molten aluminum alloy into a steel mold cavity at high pressure, followed by solidification and ejection of the casting.

It is suitable for producing components with relatively simple geometries.

Aluminum Squeeze Casting: aluminum squeeze casting, also known as liquid metal forging, combines elements of casting and forging.

It involves injecting molten aluminum alloy into a preheated steel mold cavity at moderate pressure, followed by the application of high pressure to consolidate the material and eliminate porosity.

This process allows for the production of components with complex geometries and superior mechanical properties.

Mechanical Properties

Aluminum Die Casting: while die casting offers satisfactory mechanical properties, components may exhibit limitations in terms of strength, ductility, and fatigue resistance.

Aluminum Squeeze Casting: squeeze casting delivers superior mechanical properties, including heightened strength, ductility, and fatigue resistance.

The application of pressure during solidification ensures densification of the material and minimizes porosity, resulting in components with enhanced structural integrity.

The mechanical properties of squeeze castings that CEX can achieve:

Tensile Strength: 260-320MPa

Yeild Strength: 220-260MPa

Hardness: 80-110HB

Density: 2.7-2.72 g/cm3


Surface Finish and Dimensional Accuracy

Aluminum Die Casting: renowned for its excellent surface finish and dimensional accuracy, die casting is suitable for applications where aesthetics and precision are crucial.

Aluminum Squeeze Casting: squeeze casting offers comparable surface finish and dimensional accuracy to die casting, ensuring that components meet stringent specifications with minimal post-processing required.

Surface finish services that CEX can provide:


Shot Blasting

Spray Painting



Geometric Complexity

Aluminum Die Casting: die casting is well-suited for components with simpler geometries due to limitations in mould design and material flow.

Aluminum Squeeze Casting: squeeze casting excels in producing components with intricate geometries, thin walls, and complex features.

The ability to fill mould under pressure allows for optimal material distribution and the fabrication of complex shapes.

Porosity and Material Density

Aluminum Die Casting: porosity issues may arise in die cast components due to entrapped gases during rapid solidification, compromising material density and structural integrity.

Aluminum Squeeze Casting: squeeze casting minimizes porosity and enhances material density through the application of pressure during solidification.

This results in components with improved structural integrity and mechanical properties.
